Latest updates[?]: Live-fire exercises have been conducted on the USS Carl Vinson in order to test its RIM-116 Rolling Airframe Missile (RAM) and Phalanx Close-In Weapons System (CIWS). The nuclear-powered super carrier fired at two drones using the ship's aft RAM launcher and fired the CIWS as part of a pre-aim calibration firing evolution during Carrier Strike Group 1's Composite Training Unit Exercise. Crew on board said the CIWS PAC fire served a dual purpose, allowing Carl Vinson Sailors to perform a maintenance check as well as readying the mounts for a rogue drone situation.

CVN 70: Homecoming

Osama Bin Shot, Osama Bin Buried. (May 3/11)

In November 2005, Northrop Grumman Newport News in Newport News, VA was awarded a $1.94 billion cost-plus-incentive-fee contract for accomplishment of the FY 2006 mid-life refueling and complex overhaul (RCOH) of the Nimitz Class aircraft carrier USS Carl Vinson [CVN 70]. The ship was commissioned in 1982, and this effort shall provide for the accomplishment of the overhaul, alterations, repair, maintenance, and refueling of CVN 70 and its nuclear reactor plants to ensure continued safe operation of the ship. According to GlobalSecurity.org, the Carl Vinson is scheduled to remain in service until 2032.

It’s interesting to note that the US DoD comptroller’s FY 2007 “Program Acquisition Costs by Weapon System” document lists split-funding of the CVN 70 RCOH over FY 2006-2007, with a total cost of $2.89 billion. So, how does this $1 billion discrepancy resolve itself? What about all those contracts before FY 2006? And how did the program go, now that the USS Carl Vinson has returned to the fleet at last?

Latest updates[?]: Lockheed Martin will provide combat systems for Australia's new fleet of submarines. The move is said to increase interoperability with fellow Lockheed system-user the US Navy. French firm DCNS won the $38 billion Australian submarine contract back in April defeating Germany's ThyssenKrupp Marine and Japan's Mitsubishi Heavy Industries and Kawasaki Heavy Industries. Since then, the company has been dealing with the aftermath of a 22,000 page data leak of submarines they are building for India, drawing a warning from Australian defense officials.

Bridge to the future?

In its 2009 White Paper, Australia’s Department of Defence and Labor Party government looked at the progress being made in ship killing surveillance-strike complexes, and at their need to defend large sea lanes, as key drivers shaping future navies. These premises are well accepted, but the White Paper’s conclusion was a surprise. It recommended a doubling of Australia’s submarine fleet to 12 boats by 2030-2040, all of which would be a new successor design that would replace the RAN’s Collins Class submarines.

The surprise, and controversy, stem from Australia’s recent experiences. The Collins Class was designed with the strong cooperation of ThyssenKrupp’s Swedish Kockums subsidiary, and built in Australia by state-owned ASC. The class has had a checkered career, including significant difficulties with its combat systems, issues with acoustic signature and propulsion, major cost growth to A$ 5+ billion, and schedule slippage. Worse still, reports indicated that the RAN can only staff 2 of its 6 submarines. High-level attention led to a report and recommendations to improve the force, but whether they will work remains to be seen. Meanwhile, the nature of Australia’s SEA 1000 future submarine project – and its eventual cost – remain unclear, with estimated costs in the A$ 36-44 billion range. This FOCUS article covers Australia’s options, decisions, and plans, as their future submarine program slowly gets underway.

India’s submarine fleet currently consists of 16 boats: 10 Russian SSK Kilo (Sindhugosh) Class, 4 locally built SSK U209 (Shishumar) Class, a leased nuclear-powered Improved Akula Class SSN from Russia (INS Chakra), and its own INS Arihant SSBN. Most of the Kilos have been modernized, but readiness rates for India’s existing submarine fleet sits below 40%, and the U209s will have trouble lasting much beyond 2015. With Pakistan acquiring modern submarines, and Chinese submarine building exploding, expanding India’s submarine fleet became an obvious national priority.

In 2005, India confirmed that it would buy 6 Franco-Spanish Scorpene diesel submarines, with an option for 6 more and extensive technology transfer agreements. Unfortunately, 7 years after that deal was signed, “Project 75” has yet to field a single submarine. A poor Indian procurement approach, and state-run inefficiency, are pushing the country’s entire submarine force toward an aging crisis. This DID FOCUS article covers the Scorpene deal and its structure, adds key contracts and new developments, and offers insights into the larger naval picture within and beyond India.

Latest updates[?]: Huntington Ingalls has been awarded a $152 million US Navy contact for advance planning for the construction of the aircraft carrier Enterprise (CVN 80). The third aircraft carrier in the Gerald R. Ford class was named in honor of the Navy’s first nuclear-powered aircraft carrier, USS Enterprise (CVN 65). Work to be carried out includes engineering, design, planning, and procurement of long-lead-time material, and will be performed at the company’s Newport News Shipbuilding division through March 2018. Construction is to commence in 2018 and be delivered to the Navy in 2027.

USA’s Nimitz Class &UK’s Invincible Class

Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.

Nimitz Class cutaway

As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.

DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.

According to GlobalSecurity.org, India’s ATV (advanced technology vessel) program to build a nuclear-powered submarine began in 1974, and became a serious effort in 1985. The Federation of American Scientists’ December 1996 document “The Indian Strategic Nuclear Submarine Project: An Open Literature Analysis” remains one of the best single open sources on India’s program. Unfortunately, it was compiled over a decade ago and has become rather dated. That project has continued, and this DID Spotlight article continues to collect open source information on the ATV program.

More and more sources were claiming that a rented Russian Akula class boat would be operational as a training vessel by 2009. The concept was correct, but the date was not. A deadly accident during K-152 Nerpa’s sea trials delayed that project, and further complications pushed its hand-over date to 2012. As efforts to move the Nerpa into service continue, India has finally launched its indigenous nuclear sub Arihant, to begin sea trials and testing.

Latest updates[?]: The US' top shipbuilders are growing impatient with the Navy over the Ohio-class Replacement Program (SSBN-X), with General Dynamics Electric Boat and Huntington Ingalls Industries both calling for the service to comment on a proposed workshare between the two yards. The two yards submitted a proposal for a working arrangement in March, which will see Electric Boat complete the majority of work for the twelve new subs; however the Navy has yet to finalize its procurement strategy for the program, despite advanced procurement scheduled to start in 2017 after a DoD review of the Navy's acquisition strategy in mid-2016.

SSBN-X concept

The US Navy needs new SSBN nuclear missile submarines. Their existing Ohio Class boats will begin to retire at a rate of 1 hull per year, beginning in 2027, as they reach the end of their 42-year operational lifetimes. Hence SSBN-X, also known as the Ohio Replacement Program for now.

The first step toward recapitalization involved a new Common Missile Compartment and Advanced Launcher for current and future nuclear missiles. The next step involves finalizing a design that can serve effectively to 2080, without destroying the US Navy’s shipbuilding budget in the process. Good luck with that one, but they have to to try. The maintenance of the USA’s nuclear deterrent is too important, in a world where nuclear weapons are proliferating.

Latest updates[?]: South Korea unveiled a new attack submarine. The sixth 214-class sub, built by Daewoo Shipbuilding and Marine Engineering Co., is a 1,800-ton boat powered by Air Independent Propulsion. The South Koreans ordered the first batch of 214-class subs in 2000, with an additional order for six boats set for delivery by 2020. The South Korean Navy recently stood up an independent submarine command, becoming the sixth country in the world to possess such an independent structure.The command is based at Jinhae Naval Base, in South Gyeongsang, managing its fleet of 13 boats.

Sohn Won-Yil & Nimitz

The German Type 214 was selected by Korea over the French/Spanish Scorpene Class that has been ordered by Chile, India, and Malaysia. Some would argue that U-214s are the most advanced diesel-electric submarines on the market, with an increased diving depth of over 400 meters, an optimized hull and propeller design, ultra-modern internal systems, and an Air Independent Propulsion (AIP) system that lets the diesel submarine stay submerged for long periods without needing to surface and snorkel air.

South Korea ordered its first 3 KSS-II/ Type 214 boats in 2000, which were assembled by Hyundai Heavy Industries. The Batch 2 order will add 6 more of the 65m, 1,700t boats, effectively doubling the ROKN’s number of modern submarines. The latest development is a $16 million order for Saab electronic systems for the 2nd batch of 214 submarines.

Update April 10/2015:
In the midst of the United Kingdom’s election politicking, the Conservative party has promised to build four new replacement subs for the UK’s Trident nuclear deterrent. The Royal Navy currently uses SSBN Vanguard-class subs, with the UK government required to make a decision over whether to replace the current system by 2016. The debate over the UK’s nuclear deterrent program has become increasingly politicized, with the parties split over the program’s future.

Britain has announced a GBP 350 million (about $560M), 42 month contract for a 4th “complex overhaul” of its 15,000t SSBN Vanguard Class nuclear missile submarines. HMS Vengeance will require about 2.5 million man-hours of work, including installation of a new Mk.2 nuclear reactor core. As of March 2/12, the submarine was at Devonport ready to dock down, and will remain in dry dock until flood-up in late 2014.

HMS Vengeance is the last of the UK’s 4 SSBNs submarines to undergo the Long Overhaul Period and Refuel (LOP-R). HMS Vigilant has just completed hers, and departed for the sea on March 27/12. Vengeance may even mark the UK’s last-ever reactor refueling contract, as the Mk.2 reactor that powers Britain’s refitted Vanguards and new Astute Class fast attack boats never needs mid-life refueling. Vengeance’s work will reach far beyond her reactor, however…

In December 2006, France’s Defense Ministry awarded a contract for nuclear-propelled fast attack submarines to state-owned warship builder DCN and nuclear energy group Areva-TA. The contract’s total value could be as high as EUR 8.6 billion, and it is set up as an initial EUR 1.0-1.4 billion contract (reports vary), followed by 6 options (tranches conditionnelles) to cover development expenses, the production of more submarines, and through-life support during their first years of operational service.

All ships wear out over time, and the repeated squeezing and relaxing experienced by submarine hulls make their replacement times less negotiable. The USA began introducing their new-generation NSSN Virginia Class fast attack boats in 2004, and Britain’s problem-plagued SSN Astute Class followed in 2010. Now, it’s France’s turn to renew its SSN fleet, as DCNS works to supply 6 Barracuda Class submarines between 2016-2027.

Brazil’s submarines are seen as a key part of the country’s new national armaments and defense strategy, which was released on Dec 18/08. It places a higher priority on protection of Brazil’s offshore energy reserves, and sees submarines as key players in that effort. The experience of the 1982 Falklands War, in which Argentina’s entire fleet was kept in port by Britain’s nuclear fast attack boat HMS Conqueror, is often cited as instructive.

In 2008, Brazil and France signed an agreement to build 4 diesel-electric submarines (SSK), and provide assistance in developing and fielding the non-nuclear parts of 1 nuclear fast attack submarine (SSN). Key specifics, such as the presence or absence of SSK Air Independent Propulsion technologies, have yet to be made public, but the terms of the agreement leave the possibility open. Reports regarding the submarine deal’s value have varied, but the budget is now set at almost EUR 7 billion. Financing now appears to be in place, and recent releases explain the budgets, the timing, and some of the key players in Brazil’s Prosub program.
